Title: Transmitter and receiver
Inventor: FUKUDA KUNIO
IPC: H04B14/04
Filed: 1995-05-17
Abstract: PURPOSE: To correct the errors and to output the satisfactory voices by transmitting a data absence code when there is no data to be sent as the attendant data and also transmitting a code that has an error correction function for the voice data. CONSTITUTION: When an error is decided in the voice data, a voice data processing circuit 56 mutes the voice data on the reception bursts. If the data on the slow attendant channels are not included in a single slot, an error correction parity FEC 54 which is transmitted in place of an error detection parity CRC 55 is used to correct the error of the voice data through the reception processing. Thus the errors of about one bit can be corrected and therefore the possibility is reduced for execution of the mute processing of the voice data. Then the interruption of talking voices due to the temporary mute processing can be reduced.

Title: Method for testing switching life of capacitor of switch apparatus
Inventor: TAKENAKA KOUJI
IPC: G01R31/333
Filed: 1982-07-08
Abstract: PURPOSE:To shorten the number of testing days to 1/2 to make an installation inexpensive, by automatically changing over the opening and the closing circuits of a sample feeder between the operations of both circuits by a double-throw switch to continuously carry out a test. CONSTITUTION:When a control signal is applied to a sample feeder TP to close a circuit, a closing sudden current I2 is supplied to the sample feeder TP by a capacitor C. By closing the circuit, because the auxiliary normally closed contact [a contact (b)] is opened and an auxiliary normally opened contact [a contact (a)] is closed, a double-throw switch DS opens a second contact S2 to close a first contact S1. Therefore, because a shut off current I1 is supplied from a generator G and the contact (a) in the side of the contact S1 of the switch DS is closed, a trip control signal is applied to the sample feeder TP which is, in turn, opened to shut off the current I1. By opening the sample feeder TP, the contact (a) is opened while the contact (b) is closed and the contact S1 of the switch DS is opened to close the contact S2. A closing control signal is applied so as to perform the above-mentioned operation continuously and automatically.

Then, the silicon oxide film 2 is formed again on the reverse overall, and a polycrystal silicon film 8 is deposited. Then, a laser beam is projected thereon, and after melting, by performing a recrystallization, the film 8 is made to change into a single-crystallized silicon film 8. Thereon, an epitaxial layer 9, which includes the same concentration of phosphorus as the one of the single crystal silicon substrate 1, is made to grow. By polishing the surface of the wafer formed in this manner until a part of the silicon oxide film 2 is exposed, islands 10, 11 for isolating elements from others are formed. The single crystal silicon substrate 1, which comes to a host crystal of the island, and the epitaxial layer 9 of a supporting member are made of the same single crystal silicon.

Abstract: PURPOSE:To automatically adjust brightness of a display part against a variation of brightness of the periphery by absorbing light which is made incident on a photodetecting part by a fluorescent substance, and radiating the light which is reradiated and guided to a radiating part to the outside by a light radiating means. CONSTITUTION:The device consists of a photodetecting part 12 and a radiating part 14, at least the photodetecting part 12 contains a fluorescent substance, and in at least a part of the radiating part 14, a light radiating means 16 for putting a total reflection condition into disorder is provided. In such a state, light which is made incident on the photodetecting part 12 is absorbed by the fluorescent substance, and the light reradiated from the fluorescent substance in the photodetecting part 12 is guided to the radiating part 14, while repeating a total reflection in the photodetecting part 12. The light guided to the radiating part 14 reaches the light radiating means 16, while executing a total reflection in the radiating part 14, and the light whose total reflection condition is put into disorder therein is radiated to the outside. The more the light quantity which is made incident on the photodetecting part 12 is, the more the light quantity radiated to the outside by the light radiating means 16 becomes. Accordingly, in accordance with brightness in the periphery of a light source unit 10, brightness emitted by the light source unit 10 is also varied.

Title: Magnetic picture recorder and reproducer
Inventor: TAKAI SHIGEYOSHI
IPC: H04N5/94
Filed: 1981-07-29
Abstract: PURPOSE:To prevent the generation of a bass to the audio output of a TV picture receiving signal, by setting the DC level of the demodulated noise signal at a low value by means of a dropout wave detection output signal in order to prevent the overmodulation of an RF converter. CONSTITUTION:The signal obtained by delaying the dropout wave detection output waveform through an LPF7 is supplied to an amplifier 8 in the noise component period of the demodulated output waveform of a video demodulating circuit 5. The DC level is set at a low value in a prescribed period for the noise component of the output waveform of a mixing circuit 10 by the output of the amplifier 8. Thus the noise component is turned into a small signal and supplied to a clamping circuit 11. Thus the signal larger than a synchronizing chip is clipped. As a result, no noise signal larger than the video signal exists any more for the video output signal. Thus no overmodulation is caused to an RF converter 13.
